FIELD

The present embodiment generally relates to equipment arrangements for stimulating the ejection of sap and methods to stimulate the ejection of sap from sugar maples and other trees with desirable sap.

BACKGROUND

A need exists for equipment for extending the time for harvesting and collecting sap from trees. Sap is generally harvested using spouts, also sometimes referred to as spiles, which are inserted into corresponding tapped holes made on the trunks of trees during the periods of tree dormancy. The sap flows out of the trees through the spouts and is further collected thereafter. Some implementations use buckets or the like in which the sap can drip by gravity and accumulate underneath the spouts. Other implementations use a vacuum system which draws the sap to a central sap processing facility.

A need has existed to improve the period of time that sap will flow from trees, and for the collection of sap with equipment that does not harm a tree. Sap collection can be obtained from all species of maple, walnut, butternut, basswood, hickory and potentially other tree general.

DETAILED DESCRIPTION OF THE EMBODIMENTS

Before explaining the present system in detail, it is to be understood that the system is not limited to the particular embodiments and that it can be practiced or carried out in various ways.

The invention relates to a system for artificially stimulating sap production in certain trees generally by applying heat to, or by chilling, a portion of individual tree trunks that are in contact with the ground.

A need has existed for increased tree sap production during the period of tree dormancy, in frozen daytime conditions and in warm nighttime conditions, and wherein the stimulated sap production during the dormancy period ranges from a fifth of an average day of production during the traditional sap season, up to one and a half times an average day of production during the traditional sap season, depending on ambient weather conditions.

A need has existed to increase tree sap production for maple, walnut, butternut, basswood, hickory and potentially other trees.

The invention enables an operator to only heat or chill a portion of the tree trunk of certain types of trees in order for sap production to be stimulated.

In embodiments, an expandable insulation shell or plastic cover would be added on top of the flexible tubing and metal liner, in order to create a layer of heated or chilled air as insulation, and to act as a wind break.

To accommodate the tapping of trees in different locations every year a “closable porthole” design for this shell can be used.

The invention relates to sap processing steps using a main boiler and a main chiller wherein a central boiler will heat a fluid that would be pumped out to the forest and a central chiller will chill a fluid that would be pumped out to the forest.

The invention relates to a method for artificially stimulating sap production in certain trees by applying cold and removing heat from a small portion of individual tree trunks that are in contact with the ground.

In embodiments, cold nighttime temperatures could freeze the tree, and then a portion of the tree trunk could be heated during the day, causing the sap to flow. It is anticipated that this daytime heating would be especially effective in areas where the daytime temperatures are close but not quite warm enough to thaw the sap during the day.

In embodiments, a portion of the tree trunk could be chilled during the night and then the warm daytime temperatures could heat the tree, causing the sap to flow. It is anticipated that this chilling overnight would be especially effective in areas where the nighttime temperatures are close but not quite cold enough to freeze the sap overnight.

The invention includes a method for distributing a heated fluid from a main boiler or for distributing a chilled fluid from a main chiller to one or more trees in a controlled manner.

In embodiments, multiple trees for treatment using heat or cold are spread out over a wide area, sometimes as much as 1,000 acres or more.

The invention for groups of trees includes an embodiment referred to herein as a “tree heating loop”, which includes certain components for groups of trees, such as 25 sugar maple trees.

In embodiments, each tree heating loop will include a heat exchanger that transfers heat from a boiler to the tree heating fluid, a controller that takes the temperature of the tree heating fluid and turns the heat exchanger on or off as required, and a fluid pump, such as a water pump, that continuously pumps the tree heating fluid through a supply hose that runs to the trees, and through a return hose that runs back to the heat exchanger.

In embodiments, the plastic tubing, fittings and equipment that are used to collect tree sap from groups of trees can be referred to herein as a “sap collection loop”, which includes certain components for groups of trees, such as 25 sugar maple trees.

In embodiments, each sap collection loop will include a vacuum pump in a sap processing facility that will create a vacuum in plastic tubing that will be connected to spouts in the trees and will draw sap through the plastic tubing into a sap processing facility. The vacuum pump will also be connected to a sap extractor that will extract the sap from the plastic tubing into a sap storage tank, while maintaining the vacuum in the plastic tubing.

In embodiments, each sap collection loop will be bundled together with a heating fluid return hose within an insulated cover.

Other factors could also affect the controller, including a timer and sap or fluid flow volumes, as necessary.

In embodiments, by freezing the sap in the trees using a chiller, the chiller will work to stimulate sap production, and the waste heat from the chiller can be used in a concentrated sap heating process.

An embodiment of the invention includes a method for using waste heat when using a chiller to freeze the sap in the trees, by using a heat sink with the chiller.

The chiller introduces a new source of waste heat that can be recycled through the invention. When running the chiller, instead of venting its heat, a heat sink can be used to store the waste heat. After the chiller has been turned off, the sap in the trees will thaw and begin to flow. After having been run through a reverse osmosis filter, the concentrated sap can be run through the heat sink to preheat it before it goes into the evaporator for boiling.

The controller can be used in this system to determine if more heat must be removed from the hot freeze resistant fluid before sending the freeze resistant fluid into a chiller.

The invention can include a condenser to attach to evaporators, to condense the water vapor that is produced by the evaporator, to produce more pure water that can be bottled and sold.

In embodiments, a water vapor condenser can be used as a heat exchanger, heating up the concentrated sap before the concentrated sap enters the evaporator for boiling.

In embodiments, the system can use solar heating. An optimized parabolic solar collector facility can be used to heat the fluids of this system.

Each day, the boiler fluid would be pumped through the forest for a while before any sap flows, and the sap will continue to flow after the boiler fluid pump is shut off. The solar heating could be sequentially or synchronously performed on the boiler fluid flow and the concentrated sap flow.

In embodiments, the system can use waste heat from the equipment of the system, such as bottling machines.

In embodiments, the system can use a heat sink that can use waste heat from the evaporator and the bottling machine to: first, pre-heat the collected sap after it has been concentrated by the reverse osmosis filter, but before the concentrated sap is injected into the evaporator, and/or second, boost the heat of the boiler fluid after it has completed a circuit through the forest, and before the boiler fluid goes through the main boiler for primary heating.

The system to stimulate tree sap self-ejection from a tree prevents fires in the forest, by controlling heat to and from tree trunks without the need for open flame near the trees or in the forest.

The system to stimulate tree sap self-ejection from a tree protects wildlife in the forest by providing the means to cause sap flow in trees without adding smoke to the air or using uncontrolled and unmonitored heating devices.

The invention creates an artificial, controlled freeze/thaw cycle, which enables the economical production of pure water and syrup in fall, winter and spring, during the entire period of time that sap producing trees are dormant. The inventive system lengthens the syrup production season.

The invention makes the production of pure water and syrup more economical, enabling the extraction of pure water from alternative, relatively small distributed sources, instead of using the water from one localized natural source (e.g. a stream) or by draining an aquifer. The system enables widespread use of a source of pure water that is distributed over a very large geographical area.

The system enables the economical production of pure water and syrup in locations that far exceed the current geographic limit of syrup production. The system expands the geographical syrup production area and enables jobs to be created in remote areas where agricultural activities do not exist.

The system provides a measure of protecting current syrup producers against climate change and the vagaries of local weather conditions, by creating stable freeze/thaw cycles that will result in known quantities of pure water and syrup production. The system takes the production quantity risk out of syrup production. This will make participation in this industry more attractive to landowners and lenders and encourage new entrants to the industry.

The invention allows syrup operators to use their land and the capital equipment that they have already deployed to produce more pure water and syrup. The system allows for more efficient use of capital that is already deployed.

The system enables enough tree sap production that economies of scale for tree syrups other than maple can be reached, so that pure tree syrups such as walnut syrup, basswood syrup, hickory syrup and others will be mass produced. The system enables the economic mass production of tree syrups other than maple.

Use of the invention will require the engagement of workers for a much longer period than the traditional sap production period, which is typically 6 to 12 weeks in the spring, providing them with gainful employment. The invention will produce much longer employment periods of seasonal workers.

The system uses waste heat effectively to minimize the amount of energy needed to produce pure water and syrup.

The invention uses renewable energy to supply the heat and/or cooling that is needed to stimulate sap production, and to supply the heat that is needed to evaporate water from tree sap to create syrup, preventing either a) greenhouse gas production through the combustion of fossil fuels to supply heat, or b) the creation of a large electric load on power grids in remote locations. The invention prevents the cost and difficulty of serving large and remote electrical loads.

EXAMPLE

In an embodiment, the system to stimulate self-ejection of tree sap from at least one live tree with a tree trunk can operate on live trees such as sugar maple trees with a minimum diameter at breast height of 10 inches, but could be as large as 70 inches in diameter at breast height or more.

Each tree can have a tree trunk with a tree trunk segment from 2 feet to 7 feet.

In this example, a metal liner such as a layer of aluminum foil such as Handi-Foil All Purpose Aluminum Foil can be wrapped around the tree trunk segment.

In this example, 6 trees are wrapped with a metal liner of aluminum foil around tree segments. Each tree will be wrapped to a height of 6 feet encapsulating each segment of the tree trunk for each live tree.

In this example, at least one flexible tube such as radiant heat tubing, namely a type of cross-linked polyethylene (PEX) tubing such as Everhot ½″ Oxygen Barrier PEX Tubing is wound around each metal liner with an outer diameter of 0.625 inches and an inner diameter of 0.485 inches.

In this example, each tree has generally the same diameter, and 50 feet of tubing is helically wrapped round each segment of the tree trunk. In an embodiment, between 30 feet and 100 feet of tubing can be used on each segment of the tree trunk, depending on the diameter of the tree and height of the segment of the tree trunk. The flexible tubes can have an inner diameter of 0.25 inch-1 inch to ensure flowability of fluid through the tubes.

Each flexible tube per tree continuously receiving sequentially either a heated freeze resistant fluid or a chilled freeze resistant fluid during the period from Nov. 1, 2019 to Mar. 31, 2020.

The heated freeze resistant fluid can be a water/ethylene glycol mix. The concentration of ethylene glycol could vary according to the local ambient temperature range of a forest. For example, if the local ambient temperature range goes as low as minus 35 degrees Fahrenheit, a 50/50 water/ethylene glycol mix will be used. If the local ambient temperature range goes as low as minus 10 degrees Fahrenheit, a 60/40 water/ethylene glycol mix will be used. Liquid “antifreeze” for car radiators also can be used.

In this example, the heated freeze resistant fluid resists solidification at temperatures from minus 76 degrees to 32 degrees Fahrenheit.

After winding the flexible tubes around the tree, the flexible tubes are connected to hoses.

The supply and return hoses can be a plastic hose of varying diameter, connecting the flexible tubes at each tree to the heat exchanger. These tubes vary in size anywhere from ¾″ for the lateral lines connecting directly to the trees, up to 2″ for the mainlines that come into the processing facility. They should be insulated with foam rubber and can be a type of cross-linked polyethylene (PEX) tubing such as Everhot ¾″ Oxygen Barrier PEX Tubing.

In this example the supply and return hoses are ¾ inch hoses with an outer diameter of 0.875 inches and in inner diameter of 0.681 inches for an increased flow rate.

A shell forming an insulation layer of air is installed over the flexible tubes over the metal liner. The layer of air insulation traps the heat that is being supplied to the segment of tree trunk by the flexible tubes.

In this example, the layer of air can be created by multiple layers of bubble wrap insulation such as rFOIL 2290 Standard Reflective Duct Insulation, such as those made by Covertech Flexible Packaging of Canada.

The shell could be another material such as mineral wool insulation. The mineral wool is water resistant.

An optional layer of plastic could be placed over the mineral wool in embodiments.

A heat exchanger is fluidly connected to a plurality of supply and return hoses engaging each of the flexible tubes.

The heat exchanger in this example is a buffer tank, positioned between the main boiler and main chiller, and the hoses connected to the flexible tubes at the trees. This buffer tank could be a 30 gallon or a 200 gallon T2 Thermo2000 BuffMax Buffer Tank. The buffer tank in this example is a 30 gallon tank.

The buffer tank is configured to: receive superheated fluid from a first source such as a high efficiency modulating condensing boiler known as the “combi” NTI Boiler Model# TX151C.

The heat exchanger transmits a heated freeze resistant fluid at a target temperature to the supply hose and then to the at least one flexible tubes wound around each of the six trees and the heat exchanger receives a reduced temperature heated freeze resistant fluid, reduced in temperature from 1 to 200 degrees Fahrenheit from the return hose from each of the six trees.

During November 1 to December 31 in North America, and also during February 15 to April 30 in North America the heat exchanger can receive superchilled fluid from a second source and transmit a chilled freeze resistant fluid 66 at a target temperature to the supply hose and then to the at least one flexible tube wound around at least one tree and receive an increased temperature chilled freeze resistant fluid 67 increased in temperature from 1 to 100 degrees Fahrenheit from the return hose.

In this example of 6 trees, a first fluid pump fluidly connects between the heat exchanger and the supply and return hoses and a second fluid pump connects between the first source, the main boiler, and the heat exchanger. The main boiler can be a high efficiency modulating condensing boiler such as the “combi” NTI Boiler Model# TX151C

The fluid pumps are devices to move fluid by mechanical action, such as an electric, rotary positive displacement pump. In this example, the fluid pump connected between the heat exchanger and the hoses could be a Grundfos UPS 26-29 FC Nonsubmersible Circulation Pump (3-speed, rating ⅙ HP), and the fluid pump connected between the boiler and the heat exchanger could be a Grundfos UPS 15-58 FC Nonsubmersible Circulation Pump (3-speed, rating 1/25 HP).

A controller such as a laptop such as a Lenovo Laptop IdeaPad™ is electronically connected to the heat exchanger and to the fluid pump.

The controller includes a first processor which in this example is an AMD A9-9425 3.1 GHz processor.

The controller includes a first data storage amounting to 8 GB of memory.

In the first data storage is a library which in this example can be an Excel file containing tables of data including date, time, historical ambient temperature, historical weather conditions, historical heating fluid target temperatures, historical heating fluid target flow rates, and historical tree sap flow rates.

For this example of 6 trees in Haliburton County in the Province of Ontario Canada the historical target temperature ranges for the freeze resistant fluid by date and time for the forest can be 100 degrees Fahrenheit to 200 degrees Fahrenheit; historical target fluid flow rates can be 10 gallons per minute to 100 gallons per minute; historical ambient temperatures by date and time for the forest can be minus 40 degrees Fahrenheit to 100 degrees Fahrenheit; historical weather conditions by date and time for the forest can be sunny, 20% to 80% overcast, cloudy, rainy, snowy, windy; historical sap flow rates by date and time for the forest can be from one half of a pint per day to a gallon per day or more.

In this example, the controller uses a Sap Flow Model software program to calculate the target fluid temperature range and the target fluid flow rate that would maximize the sap flow rate for the forest at a date and time.

In this example, the Sap Flow Model algorithm for the target fluid temperature is: Target fluid temperature (deg F.)=180 F−(local ambient temperature+30)*(1 if sunny=yes, 0.5 if sunny=no)+(20 F*(1 if windy=yes, 0 if windy=no))

In this example, the Sap Flow Model algorithm for the target fluid flow rate is: Target fluid flow rate=If (sunny=no and windy=yes), then “high” (30 GPM), else if (sunny=no and windy=no) or (sunny=yes and windy=yes), then “medium” (20 GPM), Else “low” (10 GPM).

In this example, the controller is connected to the heat exchanger and to the fluid pumps by the internet. Using the results of the Sap Flow Model, the controller sets the target fluid temperature on the buffer tank and sets the target fluid flow rate on the fluid pumps. In this example, these settings are updated every 30 minutes.
